启动容器并挂载数据卷

  1. mkdir -p /dockerapp/nginx/www /dockerapp/ngxin/conf /dockerapp/nginx/logs
  4. docker run -it -p 8081:80 --name dockerapp01 -v /dockerapp/nginx/conf:/etc/nginx 4f361dbcbce5 /bin/bash

无法访问

  1. curl localhost:8081
  2. curl: (56) Recv failure: Connection reset by peer

防火墙状态正常

  23. [root@--- financial-innovation-h5]#
  1. 在nginx镜像基础之上把自己的前端项目打包成镜像
  2. 运行镜像，启动容器
  3. 浏览器访问
    1. FROM nginx:1.17.3
    2. ADD h5.tar.gz /usr/share/nginx/html

步骤上没有任何问题，没有参考任何文档，实测发现容器启动了，但是容器里面的nginx服务并没有启动，导致内网和浏览器访问不同，
解决：
进入容器，启动服务

  1. cd /etc/init.d
  2. .nginx start

浏览器即可访问

启动容器跟启动容器内的服务是两码事

守护态运行

  1. docker run -d ubuntu:18.04 /bin/sh -c "while true; do echo hello world; sleep 1; done"

问题扩展 怎么接上Jenkins，完成CI/CD
